Abstract

PURPOSE:To provide the titled transfer foil rich in three-dimensional feeling, by sequentially laminating a releasable layer and a transparent colored layer on one side of a synthetic resin base film, providing a vapor-deposited layer thereon, and providing thereon an adhesive layer having the same shape as that of the vapor-deposited layer and a specified thickness. CONSTITUTION:The releasable layer 2 consisting of a synthetic resin or an admixture thereof with a releasing agent is laminated on one side of the base film 1 formed from polypropylene, a polyester or the like. The colored layer 3 consisting of a synthetic resin or an admixture thereof with a coloring agent is laminated on the releasable layer 2, and the vapor-deposited layer 4 consisting of aluminum and having the shape of characters or a pattern is partially provided on the layer 3. The adhesive layer 5 consisting of a synthetic resin and having the same size and shape as those of the layer 4 is provided on the layer 4, in a thickness of 10-30mum. When transfer is conducted on a molded article 6 by using the transfer foil thus obtained, the adhesive layer 5, the vapor- deposited metallic layer 4, the colored layer 3 and the releasable layer 2 in a predetermined shape are transferred onto the surface of the article 6, resulting in a metallic luster part which is raised and rich in three-dimensional feeling.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative transfer foil, and more particularly, a peelable layer provided on a base film and a transparent colored layer are partially provided with a metal vapor deposited layer and an adhesive layer, It relates to a transfer foil that has a rich three-dimensional effect that rises from the surface of the molded product when it is transferred to the molded product.

Generally, as a method of forming characters or patterns with metallic luster on the surface of a molded product, a release layer, a colored layer, a metal vapor deposition layer, and an adhesive layer are sequentially laminated and integrated on one side of a synthetic resin base film. Using a transfer foil, the surface of the molded product is heated and pressurized by engraving a convex letter or pattern, and then the base film is peeled off to obtain a desired decorative surface.

However, in conventional transfer foils, each layer is approximately a release layer ~
0.02μ, colored layer ~2μ, metal vapor deposited layer ~0.05μ,
Since the adhesive layer is composed of a thickness of about 2 μm, after the transferred base film is peeled off, the thickness of the transfer layer remaining on the molded product surface is as thin as 3 to 6 μm, and there is no step difference with the molded product surface, creating a three-dimensional shape. The finish υ was lacking in taste.

On the other hand, as a method to obtain a decorative surface with a metallic luster color that gives a three-dimensional effect, it is possible to apply a metallic luster color to the white part of the molded product, in which the υ letter or pattern part is integrally formed in a convex shape using a mold. A method of obtaining a decorative surface by performing transfer using transfer foil, or
A method is used in which a decorative surface is obtained by forming convex portions with ink on the surface of the molded product using a printing method such as silk screen, and then transferring the white portion using a transfer foil that has a metallic luster color on the entire surface. . However, in the former case, it is necessary to form a concave part in the mold that corresponds to the convex part of the molded product by a method such as corrosion, chiseling, or engraving, which causes problems in terms of production time and production cost. was there. In addition, in the latter case, since the two-step process of printing and then transfer is applied, production costs are also affected by the type of printing ink, drying temperature, and There were problems such as restrictions on drying time.

The object of the invention is to improve the above-mentioned conventional problems and to provide a transfer foil that has an extremely simple structure and can transfer a raised and three-dimensional transfer layer to a molded product. be.

That is, the transfer foil of the present invention includes a release layer provided on one side of a synthetic resin base film, a transparent colored layer provided on this release layer, and a vapor deposition layer partially provided on this colored layer. , and an adhesive layer having a thickness of 10 to 30 μm provided on the vapor deposition layer in the same shape as the vapor deposition layer.

The invention will now be described with reference to the accompanying drawings, which illustrate one embodiment of the invention.

In FIG. 1, the base film 1 is made of a stretched or unstretched synthetic resin film such as polyester, polyester, etc., and the entire surface of one side of the base film 1 is coated with acrylic, vinyl, chlorinated rubber, etc. synthetic resin,
Alternatively, a release layer 2 with a thickness of about 0.02μ made by adding a mold release agent such as silicone or wax to the base film 1
It is laminated so that it can be peeled off. Further, on the upper surface of the release layer 2, a colored layer 3 having a thickness of about 2 μm is laminated, which is made of a synthetic resin such as acrylic, polyurethane, or chlorinated rubber, or a coloring agent such as a dye or pigment added thereto. On this colored layer 3, a vapor deposited layer 4 made of aluminum having a thickness of about 0.05 μm is partially vapor deposited, for example, in the shape of letters or patterns.
is provided. Further, on this vapor deposition layer 4, an adhesive layer 5 made of a synthetic resin having the same size and shape as the vapor deposition layer 4 and having high adhesion to the vapor deposition layer 4 and high adhesion to the molded product is provided. There is. And the thickness of the adhesive layer 5 is 10~
A thickness of 3°μ is necessary to create a three-dimensional effect when transferred to a molded product. That is, the thickness of the adhesive layer 5 is 10
If it is less than 30 μm, the swelling 9 will be poor when transferred to a molded product, and on the other hand, if it exceeds 30 μm, the drying time of the synthetic resin forming the adhesive layer 5 will be longer. Note that the adhesive layer 5 has a thickness of 10 to 30
Since the film thickness is μ compared to other layers, the screen method is suitable for forming the layer shape ZZ. The release layer 2 and colored layer 3 other than the adhesive layer may be formed by either a gravure method or a screen method. Also,
As the synthetic resin forming the adhesive layer 5, acrylic, polyvinyl acetate, salt-vinyl acetate, etc. are used depending on the material of the molded article 6, which is the object to be transferred.

When transferring to the molded product 6 using the transfer foil configured as described above, the transfer foil is placed on the molded product 6 so that the adhesive layer 5 corresponds to the surface of the molded product 6, and then the heated silicone rubber After pressure adhesion using a roll or lithographic stamp, etc., the base film 1 is cooled and peeled off. As shown in FIG. 5. Coloring layer 3 and release layer 2 according to the shape of metal vapor deposited layer 4
is transferred to the surface of the formed product 6, and the other parts are the base film 1.
A metallic luster part with a rich three-dimensional effect and a desired bulge is obtained with a residual layer on the side.

As described above, according to the present invention, since the metal vapor deposited layer and the adhesive layer are completely formed on the transfer foil in the desired shape in advance,
Instead of integrally forming protrusions on the surface of the molded product or using stamps with protrusions of the desired shape, as in the past, metals and metals of a predetermined shape can be formed simply by pressure transfer using a planar heating element. A glossy area can be obtained, and usually an adhesive layer of about 2μ thick is applied once.
Because it is formed thickly (0 to 30μ), it does not transfer to the printed part after printing on the surface of the molded product as in conventional methods.
Kj&,? on the surface of the molded product only in the transfer process? The top has υ,
This has the effect of providing a metallic lustrous part with a rich three-dimensional effect.
